JENS L. JENSEN, OFOOPENHAGEN, DENMARK.

CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 260,686, dated July 4, 1882,

I Application filed February 1, 1882. (No model.)

To all whom it may concern Be it known that I, JENs LUDVIGr J ENSEN, a subject of the King of Denmark, residing at the city of Copenhagen, in the Kingdom of Denmark, have invented certain new and use ful Improvements ,in Cultivators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, andto theletters or figures of reference marked thereon, which form a part of this specification.

My invention has relation to that class of so-oalled walking-cultivators, for cultivating potatoes and other plants which are grown in hills, in which the mold-boards are made adjustable upon a fixed vertical pintle and provided with hinged wings or extensions on their inner sides and it consists in the detailed construction and arrangement of the said hinged wings, and also in the detailed construction and arrangement of the adjustable fender or fender-bar for lifting the leaves .of the plants as the machine advances, and thus preventing covering them, substantially as hereinafter more fully described, and particularly pointed out in the claims.

In the accompanying drawings,Figurel represents a side elevation of my improved cultivator. Fig.2 is a plan or top view of the same, and Fig. 3 is a detail view of one of the hinged wings or mold-boards with its auxiliary wing or pivoted extension.

Similar letters of reference indicate corresponding parts in all the figures.

A is the tongue, and B B the handles, which are braced to the tongue by rods B.

A and A 'are parallel vertical standards, depending from the tongue and connected by the furrow-piece or shoe 0, at the forward end of which (in front of standard A) is the arrow-headshaped plowshare '0. Back of this share, and connecting it to the tongue, is a long bolt or pintle, f, upon which a pair of wings, a a, are hinged or pivoted, and each of said wings is provided with an inwardly-projecting curved arm, g, which works through a loop or eye, h, at the rear end of the tongue. The arms 9 g are perforated, and may be held in their adjusted position by means of a pin,

i. It is obvious that the wings a a may be adjusted independent of each other, and placed either at the same or at diderent angles to the tongue by removing pin 2' and sliding either of the perforated curved arms 9 through loop h the required distance, after which the pin is reinserted to hold the arms in their adjusted position.

b b are auxiliary wings, which are pivoted upon bolts or studs 0 on the inner .side of the wings or, upon which they may be fixed in their adjusted position by means of set-screws d, fastened upon the inner side of the wings a a, and screw-threaded holes 0 in the pivoted wings I). By these auxiliary wings it will be seen that the width of the main wings or pivoted mold-boards a a may be increased in front of their flaring rear ends, thus regulating the depth of cut made by said wings on both sides of the pointed share 21. v

m is a screw-threaded tap, upon which is screwed a nut, l, in which an iron rod or arm, j, is hinged at k. This arm extends rearwardly on one side of the plow in an inclined or downward direction, and isheld in place adjusta bly by being placed between two parallel clamping-bars, a n, which are secured crosswise upon the tongue, a bolt, p, being inserted through registering-holes in bars a a and arm j. By Withdrawing the bolt or pin 19 armj may be shifted from one side of the plow to the other, or it may be adjusted at any desired angle to the central beam or tongue, A. As the plow advances this bar will operate as a fender to lift the leaves of the plants from the ground, and thus prevent covering them, and, also, by bending the stalks sidewise prevent injury to them by the hinged wings a.

q and g are a pair of shovels, the standards of which are inserted adjustably through slotted keepers r r, sliding upon a cross-bar,

objectof the adjustable arm j,which, as above stated, can be shifted to either side of the tongue and held rigidly in its adjusted position between the perforated cross-bars n n by the pin 1), is to deflect the tops of the plants as the mawith their auxiliary wings or extensions, to

throw up the hill or ridge on both sides of the central furrow.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States- 1. The combination, with the beam A, having standards A A arrow-head share o, having the shoe 0 connecting it with the rear standard, A bolt or pintlef, and adjustable wings a a, of the adjustable auxiliary wings b b and means for holding the same in their adjusted position upon wings a a, substantially as and for the purpose herein shown and set forth.

2. Ina cultivator, the combination, with a plow and plow-beam provided with the screwthreaded tap m, perforated cross-bars n n, and pin 1), of the removable fender-barj, hinged at one end in the nut l, and adjustable laterally or to either side in the perforated bars n11, substantially as and for the purpose herein shown and specified.

In testimony whereof I have hereto atfixed my signature in presence of two witnesses.

JENS LUDVIG JENSEN.
